In our training and education as Emergency Medicine providers, we often come to accept certain practice patterns as fact. When these established “facts” come along with fantastical clinical claims (don’t give your corneal abrasion patients tetracaine, it’ll melt their corneas; don’t use lido with epi for digital blocks, their finger will fall off; don’t use beta-blockers in patients on cocaine, their BP will skyrocket due to unopposed alpha-effects), we should probably look to question their supporting evidence.
